Counter-attacks by Ukrainian forces are successfully regaining territory in several areas as Russian forces regroup and refocus their efforts on operations in the east of the country.

Here are the latest developments on day 37 of the invasion:

• Ukrainian forces retaking key positions around Kyiv
• Shelling remains ongoing in Kyiv and in Chernihiv
• Russian troops said to be withdrawing from Chernobyl
• Port city of Mariupol remains likely to fall to Russia soon
• Ukrainian forces repelling Russian attacks in the Donbas
• Russia redeploying troops to Ukraine from Georgia

Russia launched its attack on 24 February, but five weeks into the war it is having to bolster its forces by redeploying troops from Georgia after suffering "unexpected losses," according to the UK Ministry of Defence (MoD).

Ukrainian counter-attacks have pushed Russian troops back in a number of places and the MoD says that Russia is struggling to sustain its operations across multiple areas of engagement.
